What is the difference between digital and analog electromagnetic signals?

There is no modulation of a Digital Circuit.
Modulation is placing information onto an analog circuit to transport that
information to a distant location to be decoded/demodulated.
Having said that, you can modulate a digital signal in dozens of ways,
(Modem) and you can also modulate an analog signal dozens of ways
(AM Radio Station, CB Radio, Walkie Talkie, FM Rock Station).
Note
What this question may really be asking about is something like:
"What are the differences between using an analog signal and a digital signal when you want to encode some information for transmission?"
so that has now been posted as a separate question.

What is difference between digital image processing and digital signal processing?
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).
What are the 2 types of electronic signals?
digital and analog
Will a set top box improve signal quality for your TV?
Set top box is basically used to convert the digital signals broadcasted by digital signal broadcasters to analog signals, in case you wish to have your analog tv, but would like to have an access to digital channels. Digital channels definitely have better quality signals than analog and therefore you will have a better picture quality and signal quality even though you have converted the digital signals to analog.
How can I save digital TV signals to a hard disk?
You can install a Digital TV Tuner in your computer.
Which device is used to convert digital signals to analog signals or analog signals to digital signals?
The set top box that your provider gives you is what converts the Digital signal to the analog signal. The digital signal is compressed at the provider and sent to the end user. The "tuner" (which can be built into a tv, a set top box or a cable card) Then decompresses the digital signal and converts it into an analog signal. There is much more to this did not know how technical you wanted your answer.
What is the basic difference between analog and digital system?
analog signals are continuous but digital signals are discreet. Digital signals have only binary value like zero(off state) or one(on state).
What is the fundamental difference between electromagnetic waves and other waves?
they dont send out magnetic signals
The device that reconciles the difference between computers and phones is the a.TcpIp b.LAN c.Wand reader d.Modem?
d. Modem It modulates digital signals to analogue signals and demodulates analogue signals back to digital signals.
What is the difference between a digital box and a digital adapter?
The digital box processes digital-quality signals, with this you have access to on screen channel guides. A digital adapter provides digital-quality signals, with this you cannot access on screen channel guides.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
What is difference between digital signals and non continuous signals?
hi, actually non-continuous signals is one of a characteristics which define a Digital Signal.#non-continuous means having a finite or countably infinite number of values, which is exactly a defining property of a digital signal. therefor its not right (wrong) to ask the difference between the two.hope it help. :)
Why do digital signal require timing signals?
To measure time between digital signals.
Why is there less interference with digital signals than analog signals?
Analog signals require higher fidelity than digital signals because digital are either on or off while analog are continuous. A small difference in an analog signal is not detectable while it requires a large difference to turn on into off (digital signal). Error correction is easier with digital signals.
What is the difference between digital and analog signals in tabular form?
If we discuss the different between these two forms of the signals that is; analog and digital then we should discuss it in different aspects such as working, their architectures, pros and cons as well. The major differences among the two signals are listed below
What is the difference between broadband and a broadcast?
Broadband involves sending multiple signals on multiple frequencies. Broadcast involves using radio waves also known as electromagnetic radiation to send signals.
How do you receive digital signals?
The carrier waves are electromagnetic in nature, and it is the modulation of them that carries the information. There are several methods of modulation, FM, AM, Pulse-code, and many more. The digital signals are modulated on the carrier wave. And digital signals should theoretically be more immune to interference than analog ones.
What is the difference between AGND and DGND?
AGND means Analog ground & DGND means Digital ground. Due to fast switching of digital signals it is possible for noise generation which affect nearby analog signals.(If common gnd used for both analog & digital). If separate gnd used for both the signals.Noise will not affect the signals.
